Precast Concrete, CTF-9A Admixture, Compressive Strength WorkabilityAbstract
The addition of admixtures to precast concrete is one method to enhance performance and production efficiency. This study aims to evaluate the effect of using CTF-9A chemical admixture on the mechanical properties and early hardening characteristics of precast concrete. The methodology includes testing compressive strength, setting time, and workability of concrete with varying doses of CTF-9A in a standard concrete mix. The results indicate that the optimal dosage of CTF-9A can increase compressive strength by up to 12% compared to normal design concrete, accelerate the initial setting time, and maintain slump within an applicable time frame for precast operations. Therefore, CTF-9A shows potential as an effective admixture to improve the quality and productivity of the precast concrete industry.
